Hi all, I hope someone could enlighten me... How could I resolve the fact that the volume controls of all the headphones I try on CentOS 7 are not working, they are OK on CentOS 6 but impossible to make them work on my Thinkpad Laptop with an iPhone headphones or a Marshal Monitor plugged with a jack connector... Those 2 headphones work correctly in CentOS 6... What could I do to get the same behavior on CentOS 7 and this damned Gnome 3 ? Thanks for your help... -- (°- //\ Bernie v_/_ The Mad Axeman
